Abstract
A mount for an arc discharge lamp has a cathode thereon which is encircled by a disintegration shield. The shield has a narrow gap between its ends with a mercury-containing metal capsule in the gap. The capsule is comprised of a metal cup having a larger diameter portion and a smaller diameter portion, the larger diameter portion having been flattened and sealed after the mercury has been dispensed into the capsule. The flattened larger diameter portion of the capsule is welded across the gap of the shield.
